Description
Technical field
The utility model relates to traffic information collection technical field, refers in particular to a kind of crossing traffic information harvester.
Background technology
Effective traffic information collection is deciding factor road management person being grasped to road conditions in real time.
Traditional traffic information collection utilizes one group of coil, electric wire and teleseme composition, and coil is embedded in underground induction through vehicle herein, and electric wire continued power also transmits electric signal frequently to teleseme.There is the perishable not easy care of coil when gathering in this traffic information collection mode, the problems such as loaded down with trivial details installed by coil.
Utility model content
In order to solve traditional problem that intersection information harvester collecting efficiency is low, operability is low, the utility model proposes a kind of crossing traffic information harvester, obtainable data class is abundanter, and easy for installation, maintenance cost is low, easy and simple to handle, collecting efficiency is high, long service life.
The technical scheme that the utility model adopts is: a kind of crossing traffic information harvester, comprise at least one collector and teleseme, described collector comprises web camera, virtual coil module and RS485 transport module, web camera, virtual coil module are electrically connected with RS485 transport module respectively, teleseme comprises signal converter, Signalized control circuit, signal converter is electrically connected with Signalized control circuit, and the RS485 transport module of collector is electrically connected with the signal converter of teleseme.
Adopt novel collector by web camera capture video shadow, use the virtual coil and intelligent analysis process analysis collection transport information established in it, transport information is converted to on-off model simultaneously, by power line carrier module, transport information and semaphore is transferred to teleseme.The transport information received is sent to remote control center by power carrier or network by the power carrier concentrator of teleseme; The on-off model received for Signalized control circuit provide numeral transport information input with the adaptive control of settling signal lamp.
As preferably, the quantity of described collector is three.The quantity of collector is arranged according to the complex situations at crossing, and three collectors that arrange of different angles are optimal selection.
As preferably, described teleseme is connected with network transmission module.Transport information is transferred to remote control center by network transmission module by teleseme.
As preferably, described network transmission module is cable-network transmission module.Transport information and video image are transferred to remote control center by cable-network transmission module by teleseme.
Preferred as another, described network transmission module is wireless network transmission module.Transport information and video image are transferred to remote control center by wireless network transmission module by teleseme.
As preferably, described collector comprises interface conversion circuit, and web camera, virtual coil module are respectively by interface conversion circuit and the electrical connection of RS485 transport module.When web camera, virtual coil module do not have RS485 interface, need interface conversion circuit to transfer, when such as only having RS232 interface, then need additionally to use RS232 to turn the interface conversion circuit settling signal conversion of RS485.
The beneficial effects of the utility model are: obtainable data class is abundanter, and easy for installation, and maintenance cost is low, easy and simple to handle, and collecting efficiency is high, long service life.
